Measure Up (MU) is an elementary grades curriculum and development project that began at CRDG in 2001. The Russian elementary curriculum was developed by V. V. Davydov and D. B. El’konin (1975a, 1975b) and translated into English. CRDG researchers have been studying the adaptation and implementation of this curriculum in a U.S. context.
Where most contemporary curricula assume number as the most basic concept, MU uses children’s everyday knowledge of measurement as the context for exploring and developing mathematics. Concepts such as unit, iteration, equality, commutativity, and transitivity are first introduced through work with non-numeric quantities of length, area, volume, and mass. This leads to work with the number line, regrouping, place value, and rational numbers.
